3 Claims. (Cl. 210-131) This invention relates to filtering or remov-' ing foreign material from liquids. It may be used in removal of particles from lubricants such as used in grinding or in force feed lubrication of machines including internal combustion engines of motor vehicles.

This invention has utility when incorporated in a chambered precipitant collection receptacle having entraining means as of horse hair, read- 9 ily cleansed or replaced.

Referring to the drawing:

Fig. 1 is a side elevation; with parts broken away, showing an embodiment of the invention in a force feed lubrication system for internal combustion engines;

Fig. 2 is a plan view on an enlarged scale of the particle remover device of Fig. 1;

Fig. 3 is a section on the line IIIIII, Fig. 2; and

Fig. 4 is a section on the line IV-IV, Fig. 3.

A machine such as a motor vehicle I is provided with a lubricating system embodying pressure or force feed of a lubricant therethrough. A filtermay be inserted in this system to have supply line 2 for delivering the lubricant thereto and a discharge line 3 for the lubricant from the filter. The intake 2 is assembled with fitting having brazed assembly 5 with closure 6 of general disk form having marginal flange I and depending skirt 8. Outlet fitting 9 connected to the discharge 3 has brazed assembly ill with end wall ll of the general structure having cylindrical side wall l2 terminating away from the end wall It in outwardly extending 6. Gasket l4, spacing these flanges I, I3, may be clamped by bolts l5 having wing nuts 16 thereon. There is thus provided a readily removable mounting. for, this closure 6 in completing the structure housing herein.

The fitting 9 has cylindrical portion I'I extending into the housing and there centering concentric tube III, which registers with inward projection l9 from the intake fitting 4.- This tube l8, adjacent the fitting portion It has lateral ports or openings 20. Remote therefrom and adjacent the fitting l1 this tube l8 has ports or openings 2|. These ports 20 and 2| are adjacent the respective inlet and outlet openings of the housing or general chamber and are spaced from each other as to the tube l8 by diaphragm 22, expanded from its dished form into anchored position as a baffle isolating the ports 20 from the ports 2| of the tube 3.. Between the fitting portion l1 and the diaphragm 22 screen 23 flange l3 opposing the flange l of the closure v is provided, which herein may have a mesh of, say fifty to seventy-five openings per inch.

The tubel8 transversely thereof andadjacent the openings 20 has transversely extending pin 24; Disk or partition 25 is perforate with series of openings 26. Furthermore, this disk 25 has central opening 21 to extend about the tube 18 and additionally'is provided with notches 28 and at an angular relation therefrom, concave seats 29. Chamber portion of this housing has therein fibrous material 3| entraining particles of material in suspension, as metal or foreign matter in the lubrication system including prodnets of corrosion and free carbon. This entraining material 3| is desirably of horse tail hair in lengths averaging, say twelve inches. This is a resilient mass which may be compressed in the chamber 30 by the partition or diaphragm 25, and as this perforate partition 25 is thrust along the tube I8 to have the pin 24 ride through the openings 28, angular shifting may occur to bring the seats 29 into register with the pin 24, with the resilient horse hair mass 3| springing this partition 25 back into locked position with the pin 24,

There isthus isolated from the chamber 30 intake chamber 32.

In the operations hereunder, pressure liquid supply as screw cutting oil or lubricant in metal workingoperations or the crank shaft cylinder lubrication oil as in a motor vehicle, enters from the pipe 2 through inlet fitting 4 to the tube l8 above the baffle 22 and fiows therefrom by thelateral ports 20 into the 'chamber 32 and with less velocity than its entrance through fitting 4, passes through the series of openings 26 into the filtering mass of hair 3|. In seeping therethrough to have the suspension particles removed, the fiow into the tube l8 below the diaphragm or baiiie 22, is permitted by the openings 2| and thence through the wire cloth 23 for pressure discharge through the fitting 9 at the outlet This horse hair under normal lubrication exposure is not prone to disintegrate. Furthermore, it is of a resilient body mass holding up even as loaded with foreign material or matters of suspension in .the oil. In service there may be ac oumulation in this filter device, which has in practice been used up to eight thousand miles in motor vehicle service with efliciency still in rev moving particle accumulation from the circulating lubricant. However, the entraining mass may be easily cleansed, for the closure 5 is readily removed by backing oil the wing nuts IS. The partition 25 is likewise readily taken out or removed by bringing the openings '28 in register with the pin 24 which allows the horse hair mass 3| to -6 expand to lift outward this partition which is readily taken away and the mass. 3| may be pulled out, shaken, washed say in gasoline and replaced.

Should the owner or operator so desire, the filler may be cast aside and a new charge placed 10 in the chamber 30, with the partition 25 reassembled as also the closure 6. The device is then in condition for continuation 01 use with no depreciation. In fact the single charge 'of horse hair with repeated cleansing at intervals may 1 have a life comparable with that of the motor vehicle. The set up in a machine or motor vehicle may be even in other than vertical position, with retention oi efliciency in operation.

What is claimed and it is desired to secure by Letters Patent is: I

1. In a device 01' the character described, the combination of a cylindrical chamber having an open end and an Opposite closed end, a concentric tube in said chamber having inlet openings adjacent said open end of the chamber and outlet openings adjacent the closed end of the chamber, said tube having a baille therein spacing said inlet openings from said outlet openings, a periorat'e partition outside the tube and in the chamber, fibrous entraining means in the chamber between the perforate partition and toward said outlet openings, said perforate partition being shiftable along the tube, holding means coacting between the tube and partition for maintaining the partition in entraining means compressing position about the tube toward the outlet openings, and a closureior the chamber open end.

, 2. In a device of the character described, the combination of a cylindrical chamber having an open end, a central tube in said chamber having 5 lateral openings therefrom into the terminal portions or the chamber, a partition in the tube spacing said openings for inlet toward one end and outlet toward the :other end, a perforate partition outside the tube, compressible fibrous en- 10 training meansin the chamber between the per-' forate partition and tube openings toward one end of the chamber, and a closure for the chamber spaced from the latter partition, adjacent which closure the other openings from the tube 15 provide a way in communication with the periorate partition.

3. In a device of the character described, the combination of a cylindrical chamber having an open end, a concentric tube in said chamber 29 having inlet openings adjacent one'end or the chamber and outlet openings adjacent the other end oi the chamber, said tube having a baflle therein spacing said inlet openings from said outlet openings, a perforate partition outside the 25 tube and in the chamber, fibrous entraining means in the chamber between the perforate partition and toward said outlet openings, said perforate partition being shiitable along the tube in entraining means compressing position about 3 the tube toward the outlet openings, and a closure for the chamber on the side of the partition toward the inlet openings.
